Question

which undefined term can contain parallel lines?
○ line
○ plane
○ point
○ ray

Explanation:

Undefined terms in geometry are basic concepts without formal definitions. A line is a 1-dimensional set of points, a point is a 0-dimensional location, and a ray is a portion of a line with one endpoint—none of these can hold two distinct parallel lines. A plane is a 2-dimensional flat surface that can contain multiple lines, including parallel lines (lines that never intersect and are coplanar).

Answer:

plane
